Abstract: BACKGROUND: Lynch syndrome is an autosomal dominantly inherited disorder caused by germline mutations in DNA mismatch repair (MMR) genes. Previous studies have shown that MMR gene mutation carriers are at increased risk of colorectal, endometrial, and several other cancers following an initial diagnosis of colorectal cancer. We estimated cancer risks following an endometrial cancer diagnosis for women carrying MMR gene mutations. METHODS: We obtained data from the Colon Cancer Family Registry for a cohort of 127 women who had a diagnosis of endometrial cancer and who carried a mutation in one of four MMR genes (30 carried a mutation in MLH1, 72 in MSH2, 22 in MSH6, and 3 in PMS2). We used the Kaplan-Meier method to estimate 10- and 20-year cumulative risks for each cancer. We estimated the age-, country-, and calendar period-specific standardized incidence ratios (SIRs) for each cancer, compared with the general population. RESULTS: Following endometrial cancer, women carrying MMR gene mutations had the following 20-year risks of other cancer cancers: colorectal cancer (48%, 95% confidence interval [CI] = 35% to 62%); cancer of the kidney, renal pelvis, or ureter (11%, 95% CI = 3% to 20%); urinary bladder cancer (9%, 95% CI = 2% to 17%); and breast cancer (11%, 95% CI = 4% to 19%). Compared with the general population, these women were at statistically significantly elevated risks of colorectal cancer (SIR = 39.9, 95% CI = 27.2 to 58.3), cancer of the kidney, renal pelvis, or ureter (SIR = 28.3, 95% CI = 11.9 to 48.6), urinary bladder cancer (SIR = 24.3, 95% CI = 8.56 to 42.9), and breast cancer (SIR = 2.51, 95% CI = 1.17 to 4.14). CONCLUSIONS: Women with Lynch syndrome who are diagnosed with endometrial cancer have increased risks of several cancers, including breast cancer.
